3. Explain the Properties of a Metallic Mineral.
Minerals classified as metallic produce metal when they are melted. Metallic minerals possess a number of properties that make them highly beneficial and valuable. Metallic minerals have the following properties:
Heat and electricity are well conducted by metallic minerals.
Metals cannot hold electrons because they are too weak. Electrons are easily lost in them.
A metallic mineral's outer surface is shiny and hard.
Minerals in the metallic state are available at room temperature in the solid form.
Sheets and wires made from metallic minerals can be moulded and stored easily.
These are the various properties of metallic minerals.
4. What are metallic minerals?

5. How do metals differ from other elements?
As listed above, metallic elements (or short metals) possess the following properties: conduct heat and electricity. The main characteristics of these materials are that they are ductile and malevolent (i.e., they can be deformed without breaking) and usually solid at room temperature (except for mercury).
